Steel skeleton construction has allowed for today's supertall skyscrapers now being built worldwide. The nomination of one structure versus another being the first skyscraper, and why, depends on what factors are stressed. The structural definition of the word skyscraper was refined later by architectural historians, based on engineering developments of

The building of tall buildings in the 1880s gave the skyscraper its first architectural movement, broadly termed the Chicago School , which developed what has been called the Commercial Style. The architect, Major William Le Baron Jenney , created a load-bearing structural frame. In this building, a steel frame supported the entire weight of the walls, instead of load-bearing walls carrying

These curtain walls either bear on the framework below or are suspended from the framework above, rather than resting on load-bearing walls of conventional construction. Some early skyscrapers have a steel frame that enables the construction of load-bearing walls taller than of those made of reinforced concrete . Modern skyscraper walls are not load-bearing , and most skyscrapers are characterized by large surface areas of windows made possible by steel frames and curtain walls. However, skyscrapers can have curtain walls that mimic conventional walls with

9504-468: The country. As of 2015, the OECD (Organization for Economic Cooperation and Development) estimated the Chengdu metropolitan area's population to be 18.1 million. In 2006, China Daily named Chengdu China's fourth-most-livable city. Some of China's most important literature comes from Chengdu. The city has been home to literary giants, such as Sima Xiangru and Yang Xiong , two masters of Fu ,
9636-646: The court accepted Liu Yan's suggestion and changed the provincial governors to state shepherds with actual recruitment and command power. In the fifth year of Chuping (194), it moved to Chengdu. At that time, the Yizhou Provincial Governor's Department was the place where the Hu people in the Western Regions were operating. Under the Han , the brocade produced in Chengdu became fashionable and
9768-648: The creation of a significant number of early skyscrapers, though none of these were steel reinforced and few remain today. Height limits and fire restrictions were later introduced. In the late 1800s, London builders found building heights limited due to issues with existing buildings. High-rise development in London is restricted at certain sites if it would obstruct protected views of St Paul's Cathedral and other historic buildings. This policy, 'St Paul's Heights', has officially been in operation since 1927. Concerns about aesthetics and fire safety had likewise hampered
9900-433: The day than autumn (October–November). The annual mean is 16.9 °C (62.4 °F), and extremes have ranged from −6.5 °C (20 °F) to 39.4 °C (102.9 °F). Chengdu is a sub-provincial city which has served as the capital of Sichuan since Chongqing 's restoration to provincial status in 1997. It has direct jurisdiction over 12 districts , 5 county-level cities and 3 counties : As of July 2013,
10032-500: The defense of Chongqing and Chengdu, which continued to cause problems for the Japanese attacks. Slow and vulnerable obsolescent Chinese fighter aircraft burning low-grade fuel were still sufficiently dangerous in the hands of capable pilots against the Japanese schnellbomber - terror bombing raiders; on 4 November 1939 for instance, Capt. Cen Zeliu ( Wade-Giles : Shen Tse-Liu ) led his 17th Fighter Squadron, 5th Fighter Group of seven cannon-equipped Dewoitine D.510 fighters in
10164-692: The development of ancient Shu culture. The Golden Mask of the Shang and Zhou dynasties at the Jinsha Site. The ancient state of Shu was the first target to be conquered by the Qin state in the process of unifying the world. King Huiwen of Qin had prepared for this for many years, and opened up the Shiniu Road (that is, the Jinniu Road) from Qin to Shu. In 316 BC, King Huiwen of Qin took advantage of
10296-651: The development of skyscrapers across continental Europe for the first half of the 20th century. By 1940, there were around 100 high-rise buildings in Europe ( List of early skyscrapers ). Some examples of these are the 43 m (141 ft) tall 1898 Witte Huis (White House) in Rotterdam ; the 51.5 m (169 ft) tall PAST Building (1906–1908) in Warsaw ; the Royal Liver Building in Liverpool, completed in 1911 and 90 m (300 ft) high;
10428-723: The distinction of launching the first serious retaliation against the Japanese homeland. During the Chinese Civil War , Chengdu was the last city on the Chinese mainland to be held by the Kuomintang. President Chiang Kai-shek and his son Chiang Ching-kuo directed the defense of the city from the Chengdu Central Military Academy ( 黄埔军校成都分校 ) until 1949, when Communist forces took the city on 27 December . The People's Liberation Army took
10560-426: The doors of Chengtu's first Protestant Mission Headquarters were opened with over one thousand people of the community attending. The first Methodist religious service was held the following Sunday with only several attendants. The first western dispensary in Sichuan was opened 3 November 1892 with sixteen patients seeking care. The mission site became so popular that a larger space was secured near Chengtu's East Gate in
10692-402: The early 1960s Bangladeshi-American structural engineer Fazlur Rahman Khan , considered the "father of tubular designs " for high-rises, discovered that the dominating rigid steel frame structure was not the only system apt for tall buildings, marking a new era of skyscraper construction in terms of multiple structural systems . His central innovation in skyscraper design and construction
10824-416: The environment and loaded structures with decorative elements and extravagant finishes. This approach to design was opposed by Fazlur Khan and he considered the designs to be whimsical rather than rational. Moreover, he considered the work to be a waste of precious natural resources. Khan's work promoted structures integrated with architecture and the least use of material resulting in the smallest impact on
10956-454: The environment. The next era of skyscrapers will focus on the environment including performance of structures, types of material, construction practices, absolute minimal use of materials/natural resources, embodied energy within the structures, and more importantly, a holistically integrated building systems approach. Modern building practices regarding supertall structures have led to the study of "vanity height". Vanity height, according to
11088-528: The first building in the world to feature a metal-framed glass curtain wall , a design element which creates light, airy interiors and has since been used the world over as a defining feature of skyscrapers". Further developments led to what many individuals and organizations consider the world's first skyscraper, the ten-story Home Insurance Building in Chicago, built in 1884–1885. While its original height of 42.1 m (138 ft) does not even qualify as
11220-617: The first year of Emperor Guangwu's reign (25 years) in the Eastern Han dynasty, Gongsun Shu established himself as the emperor in Chengdu, and the country's name was "married family". In the twelfth year of Jianwu in the Later Han dynasty (36 years), the Great Sima Wuhan of the Eastern Han dynasty finally captured Chengdu after five years of war, and his family perished. In the fifth year of Zhongping (188), Emperor Ling of Han,
11352-479: The glass façade skyscraper and, along with Norwegian Fred Severud , designed the Seagram Building in 1958, a skyscraper that is often regarded as the pinnacle of modernist high-rise architecture. Skyscraper construction surged throughout the 1960s. The impetus behind the upswing was a series of transformative innovations which made it possible for people to live and work in "cities in the sky". In
11484-475: The growing population of Chengdu, China is building a hyper-dense satellite city centered around a central mass-transit hub called the Great City where any destination within the city is within a 15-minute walk. This proto-type city is intended to provide affordable, high-quality lifestyle, which provides people-oriented spaces that does not require a car to navigate. Their current urban-planning focus in
11616-473: The hundred-story John Hancock Center and the massive 442 m (1,450 ft) Willis Tower . Other pioneers of this field include Hal Iyengar , William LeMessurier , and Minoru Yamasaki , the architect of the World Trade Center . Many buildings designed in the 70s lacked a particular style and recalled ornamentation from earlier buildings designed before the 50s. These design plans ignored
11748-555: The insurgency of the western ethnic tribes of western Sichuan. Marco Polo visited Chengdu and wrote about the Anshun Bridge or an earlier version of it. At the fall of the Ming , the rebel Zhang Xianzhong established his Great Western Kingdom ( 大西 ) with its capital at Chengdu; it lasted only from 1643 to 1646. Zhang was said to have massacred a large number of people in Chengdu and throughout Sichuan. In any case, Chengdu
11880-634: The large salt water wells of the Yangtze basin. The city logo adopted in 2011 is inspired by the Golden Sun Bird , an ancient relic unearthed in 2001 from the Jinsha Site . Archaeological discoveries at the Sanxingdui and Jinsha Site have established that the area surrounding Chengdu was inhabited over four thousand years ago, in the 18th–10th century BC. At the time of China's Xia , Shang , and Zhou dynasties , it represented
12012-453: The late Qin dynasty and was called the "Land of Abundance", and this reputation has continued to this day. During the Han dynasty, the Chengdu economy, especially its brocade industry, prospered, becoming an important source of tribute to the court. The imperial court invested in Chengdu and specially set up Jinguan management and built "Jinguan City" in the southwest of Chengdu, "Jinguan City" and "Jincheng" becoming nicknames for Chengdu. In
12144-454: The lower levels of a skyscraper will be much larger than the material required within higher levels. This is not always visually apparent. The Empire State Building 's setbacks are actually a result of the building code at the time ( 1916 Zoning Resolution ), and were not structurally required. On the other hand, John Hancock Center 's shape is uniquely the result of how it supports loads. Vertical supports can come in several types, among which
12276-459: The meeting, it was proposed he lead this contingency; having built western hospitals, Boy's and Girl's schools at Missions he established on the Yangtze and Gan Rivers from 1866 – 1888. On 9 May 1891 Dr. Virgil Hart arrived in Chengtu and two weeks later bought a home and had it subdivided into living quarters and a dispensary, for the later arriving Missionary staff to move into. On 24 June 1892,
12408-674: The most common for skyscrapers can be categorized as steel frames, concrete cores, tube within tube design, and shear walls. The wind loading on a skyscraper is also considerable. In fact, the lateral wind load imposed on supertall structures is generally the governing factor in the structural design. Wind pressure increases with height, so for very tall buildings, the loads associated with wind are larger than dead or live loads. Other vertical and horizontal loading factors come from varied, unpredictable sources, such as earthquakes. By 1895, steel had replaced cast iron as skyscrapers' structural material. Its malleability allowed it to be formed into
12540-435: The most complex encountered given the balances required between economics , engineering , and construction management. One common feature of skyscrapers is a steel framework from which curtain walls are suspended, rather than load-bearing walls of conventional construction. Most skyscrapers have a steel frame that enables them to be built taller than typical load-bearing walls of reinforced concrete. Skyscrapers usually have
12672-426: The mutual attack between Ba and Shu, and sent Sima Cuo to lead his army into Shu along the Shiniu Road, and they captured the land in a few months. After that, the king of Qin established three abolitions of Shu Hou, and finally established Shu County, and the county seat of Chengdu County was established in Chengdu, the former capital of Shu. In 311 BC, Zhang Yi of the Qin dynasty built the Chengdu city wall according to
12804-406: The performance of structures, types of materials, construction practices, absolute minimal use of materials and natural resources, energy within the structure, and a holistically integrated building systems approach. LEED is a current green building standard. Architecturally, with the movements of Postmodernism , New Urbanism and New Classical Architecture , that established since the 1980s,
12936-667: The period of the Five Dynasties, Huang Quan, a painter in Chengdu, initiated the Fine-Brush Flower-and-Bird Painting School with other painters. At that time, "Hanlin Painting Academy" was the earliest royal academy in China. Chengdu contains official, Roman Catholic and Protestant congregations, some of which are underground churches . The Apostolic Vicariate of Szechwan (now known as Roman Catholic Diocese of Chengdu )
13068-728: The price of steel decreased and labor costs increased. The steel frames become inefficient and uneconomic for supertall buildings as usable floor space is reduced for progressively larger supporting columns. Since about 1960, tubular designs have been used for high rises. This reduces the usage of material (more efficient in economic terms – Willis Tower uses a third less steel than the Empire State Building) yet allows greater height. It allows fewer interior columns, and so creates more usable floor space. It further enables buildings to take on various shapes. Elevators are characteristic to skyscrapers. In 1852 Elisha Otis introduced
13200-535: The roads will be pedestrian-oriented . This transit system provides direct transport to Chengdu itself. It is expected that the city will consume 48% less energy than cities of similar size. The goal of the 'park city' project is to allow a city like Chengdu to compete with Beijing and Shanghai without stripping the city of its character. The city of Chengdu is already known for its focus on quality of life, which includes affordable housing, good public schools, trees and bike lanes. The vast plain on which Chengdu
13332-484: The safety elevator at the E. V. Haughwout Building in New York City, allowing convenient and safe transport to buildings' upper floors. Otis later introduced the first commercial passenger elevators to the Equitable Life Building in 1870, considered by some architectural historians to be the first skyscraper. Another crucial development was the use of a steel frame instead of stone or brick, otherwise
13464-643: The safety elevator, allowing convenient and safe passenger movement to upper floors. Another crucial development was the use of a steel frame instead of stone or brick, otherwise the walls on the lower floors on a tall building would be too thick to be practical. Today major manufacturers of elevators include Otis , ThyssenKrupp , Schindler , and KONE . Advances in construction techniques have allowed skyscrapers to narrow in width, while increasing in height. Some of these new techniques include mass dampers to reduce vibrations and swaying, and gaps to allow air to pass through, reducing wind shear. Good structural design
13596-535: The second year of Emperor Ping of the Yuan dynasty, the population of Chengdu reached 76,000 households, or about 354,000 people, making it one of the most populous cities at that time. Towards the six major cities. In the third year of the reign of Emperor Jing of the Han dynasty (141 BC), the Wen Dang, the prefect of Shu County, established the world's earliest local government-run school, "Wenweng Shishi", in Chengdu. In
13728-481: The spring of 1893. This site is where the city's first Methodist church ( Sï-Shen-Tsï Methodist Church ) and hospital were built. These were later razed by rioting Chinese in 1895 and the Mission staff retreated to Chongqing and later Shanghai to escape the marauders. Dr. Virgil Hart traveled to Peking to demand redress and full payment of retribution was collected from Sichuan Viceroy Liu Ping Chang. The mission compound
13860-497: The surrounding area has sometimes taken other names, including " Yizhou ". Chinese nicknames for the city include the "Turtle City" , variously derived from the old city walls ' shape on a map or a legend that Zhang Yi had planned their course by following a turtle's tracks; the "Brocade City" (see Sichuan brocade ), a contraction of the earlier "City of the Brocade Official", after an imperial office established under
13992-407: The system of the capital Xianyang, and built a large city and a small city. In 256 BC, King Zhao of Qin appointed Li Bing as the governor of Shu County. During his tenure, he presided over the construction of the world-famous Dujiangyan Water Conservancy Project. The Chengdu Plain has been fertile and wild for thousands of miles since then. After decades of operation, Chengdu replaced Guanzhong Plain in
14124-656: The time: the A6M "Zero" fighter that dominated the skies over China against the increasingly obsolete Russian-made Polikarpov I-15/I-153s and I-16s that were the principal fighter planes of the Chinese Nationalist Air Force. This would later prove to be a rude awakening for the Allied forces in the Pacific War following the attack on Pearl Harbor . One of the first American ace fighter pilots of
14256-438: The title for six years. The design and construction of skyscrapers involves creating safe, habitable spaces in very tall buildings. The buildings must support their weight, resist wind and earthquakes, and protect occupants from fire. Yet they must also be conveniently accessible, even on the upper floors, and provide utilities and a comfortable climate for the occupants. The problems posed in skyscraper design are considered among
14388-715: The tube frame must be interrupted, with transfer girders used to maintain structural integrity. Tube structures cut down costs, at the same time allowing buildings to reach greater heights. Concrete tube-frame construction was first used in the DeWitt-Chestnut Apartment Building , completed in Chicago in 1963, and soon after in the John Hancock Center and World Trade Center . The tubular systems are fundamental to tall building design. Most buildings over 40 stories constructed since
14520-482: The tube structure was the Chestnut De-Witt apartment building, considered to be a major development in modern architecture. These new designs opened an economic door for contractors, engineers, architects, and investors, providing vast amounts of real estate space on minimal plots of land. Over the next fifteen years, many towers were built by Fazlur Rahman Khan and the " Second Chicago School ", including
14652-478: The upper rented to the lower classes. Surviving Oxyrhynchus Papyri indicate that seven-stories buildings existed in provincial towns such as in 3rd century AD Hermopolis in Roman Egypt . The skylines of many important medieval cities had large numbers of high-rise urban towers, built by the wealthy for defense and status. The residential Towers of 12th century Bologna numbered between 80 and 100 at
14784-465: The walls on the lower floors on a tall building would be too thick to be practical. An early development in this area was Oriel Chambers in Liverpool , England, built in 1864. It was only five floors high. The Royal Academy of Arts states, "critics at the time were horrified by its 'large agglomerations of protruding plate glass bubbles'. In fact, it was a precursor to Modernist architecture, being
14916-690: The war and original volunteer fighter pilot for the Chinese Nationalist Air Force, Major Huang Xinrui (nicknamed "Buffalo" by his comrades) died as a result of battling the Zero fighters along with his squadronmates Cen Zeliu and Lin Heng (younger brother of renowned architect Lin Huiyin ) defending Chengdu on 14 March 1941. Following the attack on Pearl Harbor at the end of 1941, the United States began setting up stations at airbases in China. In 1944,
15048-595: The warmer months, and relieved from both sweltering summers and freezing winters. The Qin Mountains (Qinling) to the far north help shield the city from cold Siberian winds in the winter; because of this, the short winter is milder than in the Lower Yangtze . The 24-hour daily mean temperature in January is 5.9 °C (42.6 °F), and snow is rare but there are a few periods of frost each winter. The summer
15180-617: The weight of the building. This development led to the "Chicago skeleton" form of construction. In addition to the steel frame, the Home Insurance Building also utilized fireproofing, elevators, and electrical wiring, key elements in most skyscrapers today. Burnham and Root 's 45 m (148 ft) Rand McNally Building in Chicago, 1889, was the first all-steel framed skyscraper, while Louis Sullivan 's 41 m (135 ft) Wainwright Building in St. Louis, Missouri, 1891,
15312-814: The world have more than 100 skyscrapers that are 150 m (492 ft) or taller: Hong Kong with 552 skyscrapers; Shenzhen , China with 373 skyscrapers; New York City , US with 314 skyscrapers; Dubai , UAE with 252 skyscrapers; Guangzhou , China with 188 skyscrapers; Shanghai , China with 183 skyscrapers; Tokyo , Japan with 168 skyscrapers; Kuala Lumpur , Malaysia with 156 skyscrapers; Wuhan , China with 149 skyscrapers; Chongqing , China, with 144 skyscrapers; Chicago , US, with 137 skyscrapers; Chengdu , China with 117 skyscrapers; Jakarta , Indonesia , with 112 skyscrapers; Bangkok , Thailand , with 111 skyscrapers, and Mumbai , India with 102. As of 2024, there are over 7 thousand skyscrapers over 150 m (492 ft) in height worldwide. The term "skyscraper"
15444-506: The world's largest building in terms of floor area, the New Century Global Center , is located in the city. The 100-meter-tall (330 ft) structure is 500 by 400 meters (1,600 by 1,300 ft) in size with 1,700,000 square meters (18,000,000 sq ft) of floor area, housing retail outlets, a movie theaters, offices, hotels, a water park with artificial beach and waves and a Mediterranean-style village comprising
15576-664: The world's tallest building for forty years. The first completed 417 m (1,368 ft) tall World Trade Center tower became the world's tallest building in 1972. However, it was overtaken by the Sears Tower (now Willis Tower ) in Chicago within two years. The 442 m (1,450 ft) tall Sears Tower stood as the world's tallest building for 24 years, from 1974 until 1998, until it was edged out by 452 m (1,483 ft) Petronas Twin Towers in Kuala Lumpur, which held
15708-432: The world's tallest building, New York took the lead by 1895 with the completion of the 103 m (338 ft) tall American Surety Building , leaving New York with the title of the world's tallest building for many years. Modern skyscrapers are built with steel or reinforced concrete frameworks and curtain walls of glass or polished stone . They use mechanical equipment such as water pumps and elevators . Since
15840-501: The world's top 25 cities by scientific research output , and home to the greatest number of universities and research institutes in Western China, notably Sichuan University , University of Electronic Science and Technology of China , Southwestern University of Finance and Economics , Southwest Jiaotong University , Chengdu University of Technology , Sichuan Normal University , and Xihua University . The name Chengdu
15972-476: The world, although only partially iron framed, is The Flaxmill in Shrewsbury , England. Built in 1797, it is seen as the "grandfather of skyscrapers", since its fireproof combination of cast iron columns and cast iron beams developed into the modern steel frame that made modern skyscrapers possible. In 2013 funding was confirmed to convert the derelict building into offices. In 1857, Elisha Otis introduced
16104-671: The years immediately following World War II. Early examples include Edificio España (Spain) and Torre Breda (Italy). From the 1930s onward, skyscrapers began to appear in various cities in East and Southeast Asia as well as in Latin America . Finally, they also began to be constructed in cities in Africa , the Middle East , South Asia , and Oceania from the late 1950s. Skyscraper projects after World War II typically rejected
16236-468: Was conquered by the Later Tang . The Later Shu was founded by Meng Zhixiang in 934, with its capital at Chengdu. Its second and last king, Meng Chang beautified the city by ordering hibiscus to be planted upon the city walls . The Song conquered the city in 965, introducing the first widely used paper money in the world. Su Shi praised it as "the southwestern metropolis". At the fall of
16368-679: Was established on 15 October 1696. Artus de Lionne , a French missionary of Paris Foreign Missions Society , was appointed as the first Apostolic Vicar. In 1890, the Canadian Methodist Mission was searching for more stations in Asia. In February 1891, Dr. Virgil Chittenden Hart [ zh ] , who had been Superintendent of the New York Methodist Mission Society of Central China recommended that Chengtu be its first Mission sight. During
16500-518: Was exported throughout China. A "Brocade Official" ( 錦官 ; jǐnguān ) was established to oversee its production and transaction. After the fall of the Eastern Han, Liu Bei ruled Shu Han , the southwestern of the Three Kingdoms , from Chengdu. His minister Zhuge Liang called the area the "Land of Abundance". Under the Tang , Chengdu was considered the second most prosperous city in China after Yangzhou . Both Li Bai and Du Fu lived in
16632-621: Was first applied to buildings of steel-framed construction of at least 10 stories in the late 19th century, a result of public amazement at the tall buildings being built in major American cities like New York City , Philadelphia , Boston , Chicago , Detroit , and St. Louis . The first steel-frame skyscraper was the Home Insurance Building , originally 10 stories with a height of 42 m or 138 ft, in Chicago in 1885; two additional stories were added. Some point to Philadelphia's 10-story Jayne Building (1849–50) as
16764-424: Was in 17th-century Edinburgh , Scotland, where a defensive city wall defined the boundaries of the city. Due to the restricted land area available for development, the houses increased in height instead. Buildings of 11 stories were common, and there are records of buildings as high as 14 stories. Many of the stone-built structures can still be seen today in the old town of Edinburgh. The oldest iron framed building in
16896-667: Was quickly rebuilt only to be destroyed once more in the riots of 1901. These were rebuilt a third time and later missionaries would relocate and expand the Boys' and Girls' Schools just south of the city, dedicating the Divinity College as Hart College in 1914; a part of the West China Union University , that is now Sichuan University and the West China School of Medicine (Huaxiyida). During
17028-517: Was said to have become a virtual ghost town frequented by tigers and the depopulation of Sichuan necessitated the resettlement of millions of people from other provinces during the Qing dynasty . Following the Columbian Exchange , the Chengdu Plain became one of China's principal sources of tobacco . Pi County was considered to have the highest quality in Sichuan, which was the center of
17160-664: Was the capital of Liu Bei 's Shu Han Empire during the Three Kingdoms Era, as well as several other local kingdoms during the Middle Ages. During World War II , refugees from eastern China fleeing from the Japanese settled in Chengdu. After the war, Chengdu was briefly the capital of the Nationalist republican government until it withdrew to Taipei on the island of Taiwan . Under the PRC, Chengdu's importance as
17292-454: Was the concept of the "tube" structural system , including the "framed tube", "trussed tube", and "bundled tube". His "tube concept", using all the exterior wall perimeter structure of a building to simulate a thin-walled tube, revolutionized tall building design. These systems allow greater economic efficiency, and also allow skyscrapers to take on various shapes, no longer needing to be rectangular and box-shaped. The first building to employ
17424-613: Was the first steel-framed building with soaring vertical bands to emphasize the height of the building and is therefore considered to be the first early skyscraper. In 1889, the Mole Antonelliana in Italy was 197 m (549 ft) tall. Most early skyscrapers emerged in the land-strapped areas of New York City and Chicago toward the end of the 19th century. A land boom in Melbourne , Australia between 1888 and 1891 spurred
